What You'll Learn

Primary Ingredient: Polystyrene Cement
Polystyrene cement, the primary ingredient in Citadel Plastic Glue, is a solvent-based adhesive specifically formulated to bond polystyrene plastics. Unlike general-purpose glues, it doesn't merely stick surfaces together; it chemically welds them. This unique property stems from its active ingredient, a solvent that dissolves the surface layer of polystyrene, allowing the molecules of the two pieces to fuse as the solvent evaporates.
Think of it like melting the edges of two plastic pieces and then pressing them together, creating a strong, permanent bond.
This welding action is crucial for miniature assembly, where precision and durability are paramount. Traditional glues can leave visible seams or weaken over time due to the stress of handling and painting. Polystyrene cement, however, creates a bond that's as strong as the plastic itself, ensuring your meticulously assembled models withstand the rigors of tabletop battles.
For optimal results, apply a thin layer of cement to one surface, press the pieces together firmly, and hold them in place for a few seconds. Excess cement can be easily wiped away with a damp cloth before it dries.
While incredibly effective, polystyrene cement requires careful handling. Its solvent nature means it's flammable and can irritate skin and eyes. Always work in a well-ventilated area, wear gloves, and avoid contact with your skin. Keep it out of reach of children and pets. Remember, a little goes a long way; excessive application can lead to warping or weakening of the plastic.
Compared to other adhesives, polystyrene cement offers distinct advantages for miniature hobbyists. Cyanoacrylate (super glue) can be brittle and prone to yellowing over time, while epoxy glues require mixing and have longer curing times. Polystyrene cement dries quickly, provides a strong bond, and remains invisible once dry, making it the go-to choice for achieving seamless, professional-looking miniature assemblies.
